Help please! pretty easy i just dont remember how to do it

Step-by-step explanation:

the disc. is the part under the root in the general formula

which is equal b^2 - 4 x a x c

in this equation a = 1 " coefficient of x^2"

b = 0 "coefficient of x which isn't found here "

c = 12 " the absolute "

×× = -4×12 = something i don't have a calculator

but it will be negative so the roots will be complex and unreal

:)

domain is all the x values included in the

0 ≤ x ≤ 2

range is all the y values of the graph

-2 ≤ y ≤ 2

***keep in mind that there are different ways to show domain and range

hope this !

47 - 90 = 43

43 - 180 = x

x = 137
